Abstract
A ceramic article comprises ceramic fibers having an aspect ratio of greater than 3:1 and ceramic particles. The ceramic fibers are substantially randomly oriented in three dimensions in the ceramic article. A method of forming the ceramic article includes the step of providing a composition including ceramic fibers having an aspect ratio of greater than 3:1 and ceramic particles. The composition is extruded through a multi-screw extruder having at least three intermeshing screws to form an extrudate. The extrudate is heated to form the ceramic article.
